In recent months the couple, who have been married for four years, has been subject to divorce rumors due to reports of an affair and alleged addiction issues however they are yet to publicly address these claims. A source claims Kardashian, 29, has been reaching out to Odom, 33, in the wake of his DUI drama however the former Los Angeles Clippers star is not responding.

"Lamar and Khloe have not spoken since his DUI arrest," an alleged friend of the Kardashian family told HollywoodLife.com. "He has been ignoring her calls and texts. He just can't deal with all the pressure right now."

Odom, who is rumored to have separated from Kardashian in August, was reportedly arrested and charged with DUI in Los Angeles in recent weeks and the incident fueled reports of an alleged drug addiction, according to ABC News.

The NBA veteran reportedly checked in to a rehab center on September 5 in a bid to save his basketball career.

"As much as he is looking to get better to improve his family and his marriage, the main reason he is trying to get back to a healthy lifestyle is to get back into the NBA," a source said.

"He doesn't want to be removed from the lifestyle he is accustomed to that comes with the NBA," the source continued. "But now that his options are drying up and currently nonexistent, the real reason that made him go [to rehab] was to get a job again in the NBA."

On Friday, just one day after Odom allegedly checked in to a treatment center, sources claimed he checked out. Unconfirmed reports allege the married father of two has quietly struggled with drug abuse for years and Kardashian, is said to be "fed up" with the drama surrounding their marriage.

"Khloe's not f------ around with him anymore. She's tired and fed up with the games and wants Lamar to get better so they continue on with their lives and get back to being happy," a source said.

"The DUI was a colossal setback. She thought they'd hit rock bottom, but this was a brand-new low," another source told Us magazine. "Khloe is doubtful about her marriage but wants to save his life."
